Commercial operations utilizing three-phase power grids require compatible, rugged hardware for continuous fluid transfer. Operating as a heavy duty, submersible stainless steel grey water pump, the Grundfos UNILIFT AP12.40.04.3 efficiently clears non-aggressive liquids. The system works effectively as a permanent fixture within drainage pits or as a portable unit for extracting clean and storm water on active sites.
Phase distribution allows the internal motor to maintain stable rotational torque under pressure. Wired for a 3 x 415 V supply, the robust 0.4 kW drive operates highly efficiently with a strict 1.2 Amps rated draw. It generates a consistent 233 L/Min maximum flow, discharging directly through a 40 mm female port. Against vertical pipeline resistance, the internal pressure securely sustains a 10 metre maximum head.
Transporting slightly dirty wastewater requires an unobstructed primary circulation loop. A specialized semi-open stainless steel impeller agitates the fluid, securely managing the transit of solid environmental debris up to 12 mm in diameter. This precise mechanical tolerance eliminates the risk of internal choking, allowing the pump to consistently drop fluid levels down to a 100 mm minimum clearance.
Rated strictly for submerged use, the IP68-classified housing permits deep installations down to 7 metres. An integrated motor cooling jacket constantly dissipates thermal build-up into the passing fluid, enabling the manual unit to operate safely during partial submersion. Built entirely from 304 stainless steel, it comfortably handles liquids ranging from pH 4 to 10 and temperatures up to 55°C.
